3.3.2 Your USB or ExpressCard Modem Does Not Work With the Router
• If your USB or ExpressCard modem is not working with the router, check the list of supported devices at
http://www.cradlepoint.com/modems
using must be supported on the carrier network providing your cellular service or it's considered an unsupported
device, even if it is supported on another carrier's network.
• Sometimes a USB data modem needs to be updated or have other configurations set correctly in order to make a
connection through the router. If your USB Modem has not been updated recently, it is recommended that you do
so if it is having trouble connecting to the CBA750B. Insert your USB data modem into your PC and access the
Internet using the software provided by your cellular carrier. Follow the directions provided to complete the update.
Once you have updated your USB data modem, reconnect the cellular device to your CradlePoint router and
connect to the Internet.
• If you are using a WiMAX modem, you need to set the WiMAX Realm. This can be done in the administration
pages. Log in using the hostname "cp/" or IP address "http://192.168.0.1" in your browser. Go to Internet →
Connection Manager. In the WAN Interfaces section, select your modem and click "Edit." Select the WiMAX
Settings tab and select/input your WiMAX Realm.
• Some wireless carriers provide more than one Access Point Name (APN) that a modem can connect to. If you wish
to specify the APN, this can be done on the administration pages. Log in using the hostname "cp/" or IP address
"http://192.168.0.1" in your browser. Go to Internet → Connection Manager. In the WAN Interfaces section,
select your modem and click "Edit." Select the SIM/APN Settings tab. There is an Access Point Name field: Set
the APN and click Submit. Some APN examples are isp.cingular, ecp.tmobile.com, and vpn.com. The modem
must be removed and reinserted (or the router must be rebooted) for this change to take effect.
• If the above issues have been resolved and you can connect to the router but you cannot get Internet through it
using your modem, you may need to upgrade the router firmware. Use your computer (you may need to plug your
modem directly into your computer if you don't have another way to access the Internet) to download the latest
firmware for the router at http://www.cradlepoint.com/firmware/CBA750B. Then log into the router administration
